Hays Code

Hays Code is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Hays Code rather than just read about it. In short: The Motion Picture Production Code was a set of industry guidelines for the self-censorship of content that was applied to most motion pictures released by major studios in the United States from 1934 to 1968. It is also popularly known as the Hays Code, after Will H.

Key takeaways

  • Hays Code belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Hays Code to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Hays Code from memory before moving on to harder problems.

Reference excerpt

The Motion Picture Production Code was a set of industry guidelines for the self-censorship of content that was applied to most motion pictures released by major studios in the United States from 1934 to 1968. It is also popularly known as the Hays Code, after Will H. Hays, president of the Motion Picture Producers and Distributors of America (MPPDA) from 1922 to 1945. The code spelled out unacceptable content for motion pictures produced for a public audience in the United States, such as drugs, profanity, and sex. Under Hays's leadership, the MPPDA, later the Motion Picture Association of America (MPAA) and the Motion Picture Association (MPA), adopted the Production Code in 1930 and began rigidly enforcing it in 1934. From 1934 to 1954, the code was closely associated with Joseph Breen, the administrator appointed by Hays to enforce the code in Hollywood. The film industry followed the guidelines set by the code well into the late 1950s, but it began to weaken, owing to the combined impact of television, influence from foreign films, controversial directors (such as Otto Preminger) pushing boundaries, and intervention from the courts, including the U.S. Supreme Court. In 1968, after several years of minimal enforcement, the Production Code was replaced by the MPAA film rating system.

Background

In the 1920s, Hollywood was rocked by a number of notorious scandals, such as the alleged rape and manslaughter of Virginia Rappe by popular movie star Roscoe "Fatty" Arbuckle and the murder of William Desmond Taylor, which brought widespread condemnation from religious, civic and political organizations. Many felt that the film industry had always been morally questionable, and political pressure was increasing, with legislators in 37 states introducing almost one hundred film censorship bills in 1921. In 1922, as they were faced with the prospect of having to comply with hundreds and potentially thousands of inconsistent, easily changed decency laws in order to show their films, the studios chose self-regulation as the preferable option, enlisting Presbyterian elder Will H. Hays, Postmaster General under former President Warren G. Harding and former head of the Republican National Committee, to rehabilitate Hollywood's image. The move mimicked the decision that Major League Baseball had made in hiring judge Kenesaw Mountain Landis as League Commissioner the previous year to quell questions about the integrity of baseball in the wake of the 1919 World Series gambling scandal; The New York Times even called Hays the "screen Landis". Hays was paid the lavish sum of $100,000 a year ($1.92 million in 2025), and served for 25 years as president of the Motion Picture Producers and Distributors of America (MPPDA), where he "defended the industry from attacks, recited soothing nostrums, and negotiated treaties to cease hostilities". In 1924, Hays introduced a set of recommendations dubbed "the Formula", which the studios were advised to heed, and asked filmmakers to describe to his office the plots of films they were planning on producing. In 1915, the Supreme Court had decided unanimously in Mutual Film Corporation v. Industrial Commission of Ohio that free speech did not extend to motion pictures. While there had been token attempts to clean up the films before (such as when the studios formed the National Association of the Motion Picture Industry (NAMPI) in 1916), little had come of the efforts. New York became the first state to take advantage of the Supreme Court's decision by instituting a censorship board in 1921. Virginia followed suit the following year, with eight individual states having a board by the advent of sound film, but many of these were ineffectual. By the 1920s, the New York stage, a frequent source of subsequent screen material, had topless shows, performances filled with curse words, adult subject matter, and sexually suggestive dialogue. Early in the sound system conversion process, it became apparent that what was acceptable in New York might not be so in Kansas. Filmmakers were facing the possibility that many states and cities would adopt their own codes of censorship, necessitating a multiplicity of versions of films made for national distribution. Self-censorship was deemed a preferable outcome. In 1927, Hays suggested to studio executives that they form a committee to discuss film censorship. Irving G. Thalberg of Metro-Goldwyn-Mayer, Sol Wurtzel of Fox Film Corporation, and E. H. Allen of Paramount Pictures responded by collaborating on a list they called the "Don'ts and Be Carefuls", based on items that were challenged by local censor boards. This list consisted of eleven subjects best avoided and twenty-six to be handled very carefully. The list was approved by the Federal Trade Commission (FTC), and Hays created the Studio Relations Committee (SRC) to oversee its implementation; however, there was still no way to enforce tenets. The controversy surrounding film standards came to a head in 1929.

Pre-Code In a resolution passed on June 29, 1927, the MPPDA codified lists of "don'ts" and "be carefuls" into what they colloquially called their "Magna Charta". Many of these would later become key points in the Code.

Don'ts "Those things which are included in the following list shall not appear in pictures produced by the members of this Association, irrespective of the manner in which they are treated":

Pointed profanity—by either title or lip—this includes the words God, Lord, Jesus, Christ (unless they be used reverently in connection with proper religious ceremonies), Hell, S.O.B., damn, Gawd, and every other profane and vulgar expression however it may be spelled; Any licentious or suggestive nudity—in fact or in silhouette; and any lecherous or licentious notice thereof by other characters in the picture; The illegal traffic in drugs; Any inference of sex perversion; White slavery; Miscegenation; Sex hygiene and venereal diseases; Scenes of actual childbirth—in fact or in silhouette; Children's sex organs; Ridicule of the clergy; Willful offense to any nation, race or creed;

Be Carefuls "Special care [must] be exercised in the manner in which the following subjects are treated, to the end that vulgarity and suggestiveness may be eliminated and that good taste may be emphasized":

Worked examples

Example 1 — a first encounter with Hays Code

Start with the simplest possible case. Write down what Hays Code claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Hays Code before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Hays Code ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Hays Code

In research
Hays Code appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Hays Code in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Hays Code is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1930 documents, 1930 establishments in the United States, 1968 disestablishments in the United States, so understanding it makes those chapters shorter.
In everyday life
Look for Hays Code outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
